Actions

Array

List of actions to be executed. The following actions are available:

• Change Screen
  Changes the active page. The following options are available:

  • Previous screen – if it is checked, it will go to the previous screen, otherwise you should select the page you want to display.
  • Screen – name of the page to be displayed.
  • Fade mode – selection of animation when moving from the previous page to a new page. The following options are available:
    • None – switch immediately after delay ms
    • Over left / Over right / Over top / Over bottom – move the new page over the others towards the given direction.
    • Move Left/Right/Top/Bottom – move both the old and new pages towards the given direction.
    • Fade in / Fade out – fade the new page over the old page, or vice versa.
    • Out left / Out right / Out top / Out bottom – move out the old page over the current one towards the given direction.
  • Speed – animation duration in milliseconds.
  • Delay – delay in milliseconds before the animation starts.

• Play Animation
  Animates the selected Widget property. The following options are available:

  • Target – Widget whose property is animated
  • Property – Widget property that is animated.
  • Start – initial property value.
  • End – the final value of the property.
  • Delay – delay in milliseconds before the animation starts.
  • Time – the total duration of the animation in milliseconds.
  • Relative – determines whether Start and End values are relative to the current value or are absolute values.
  • Instant – if checked apply the start value immediately, otherwise apply the start value after a delay when the animation really starts.
  • Path – determines the animation curve. The following options are available:
    • Linear – calculate the current value of an animation applying linear characteristic
    • Ease in – calculate the current value of an animation slowing down the start phase
    • Ease out – calculate the current value of an animation slowing down the end phase
    • Ease in out – calculate the current value of an animation applying an “S” characteristic (cosine)
    • Overshoot – calculate the current value of an animation with overshoot at the end
    • Bounce – calculate the current value of an animation with 3 bounces

• Set Property
  Changes the value of the selected property for the selected Widget. The following options are available:

  • Target type – The type of Widget that changes.
  • Target – Widget whose property is changed.
  • Property – the property that is being changed.
